Thanks guys. I actually have the brake adjuster bolts and they're in nice shape. They even have the paper spacers with Campy logo. I read about the half-step gearing and I think I'll at least give it a shot. Seems like I'll be needing a 5 speed freewheel for the half-step gearing so at least I've made a decision on that.

I'm still not sure about which rims/tires I should get. I know I can pretty much get whichever tires/rims I want, I just don't know enough about the models. I might go get something at the bike co-op on Thursday as a temporary solution.

edit: Also, does it look like I reassembled the rear derailleur correctly?
